Classification of elements and periodicity in properties
Understand the Problem
The question is asking about the classification of elements in the periodic table and how their properties change in a periodic manner. This includes understanding groups, periods, and trends in properties such as electronegativity, atomic radius, and ionization energy.
Answer
Classification of elements is the organization of elements in the periodic table based on recurring properties.
This refers to the organization of elements in the periodic table based on recurring properties, with elements in the same group showing similar characteristics and trends in properties across periods.

This refers to the organization of elements in the periodic table based on recurring properties, with elements in the same group showing similar characteristics and trends in properties across periods.
More Information
The periodic table was developed to systematically categorize elements based on their chemical properties. Mendeleev initially organized the elements by increasing atomic mass, though the modern table categorizes by atomic number.
Tips
A common mistake is confusing groups and periods; groups are vertical columns while periods are horizontal rows in the periodic table.
